vI MPROVEMIIN'I IN SEEDING MAGHINE.

dige Situatie notara'irtlgese @den hnelt mit multim] put nf tigt samt TO ALL WI'IOM IT MAY CONCERN:

Bc it known that I, B. A. SHEARER, of Crown Point Centre, in the county of Essex, and State of New York, have invented a now and improved Seeding Machine; and I dohereby declaro that the following is a full, clear, and exact description thereof, which will enable others skilled in the art lto make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates' to a new and improved machine for sowing seed broad-cast, and it consists of a revolving grooved cylinder, arranged or applied in a novel way, and using in connection with the same a. serios of -harrow or covering-teeth, all being applied to a fratno mounted on wheels, and` provided with a seed-hopper,

as hereinafter fully shown and described. 1n the accompanying sheet of drawings- Figure 1 is a side sectional view of my invention, taken in the lino :c :z:,'iig. 2. Eigure 2, a planer top view ofthe same. -Similar letters of reference indicate like parts.

A represents a rectangular frame, which is mounted on two wheelsB B', and has adraught-pole, C, attached. 'lhcwhecls B B are placed loosely on thciraxlc D, and one of them, B, has a toothed wheel, E, attached concontrically to it, which wheel gears into a piniolniF, at one end of the shaft of a roller, G, one end of saidshaft having its bea-ring a on the frame A, and the other end having its bearing a on a bar, H, the rear end of which is connected by ching-e, l, to the frame A, and the front end'conncctcd to a lever; II', which is on the front part ofthe `freine A, and within convenient reach of the foot of the driver when on his seat I. The bar II works in a guide, J, in which a spiral spring, e, is placed, said spring having a tendency to keep the bar II down and the pinion F in gear with the toothed wheel E of the wheel B. The roller Gis grooved longitudinally and radially,

as shown at d, and each groove d has a strip or bar, c, fitted in it and secured by set-screws f, by turning'which the capacity of the grooves d may, as regards depth, be varied as desired. K represents the seed-hopper or box, which extends the whole width of the frame A, as also does the roller G. The seed-hopper, however, is divided in this instance, but not necessarily so, by tho supports g ofthe drivcrs seat. The front side of the seed-hopper is inclined sous to -leave a quite narrow discharge opening L at its lowcr end, and this discharge opening is close to the periphery of theroller G,`as shown clearly in iig. 1. Directly behind the roller G there is an inclined chute, L, which serves as a seed-distributor. M represents o. series of bars, the front ends of 'which are fitted loosely on a rod, N, at the rear part otthe frame A. These Vbars M are allowed to rise and fall freely, or worklfreely up and down, and they -are provided each with a barrow-tooth, L. Underneath the bars M there is a transverse bar, l the-ends of which pass through pivoted .pendants O O, one at each side of the frame A, and extend forward and areattaehed to the lower end of a lever, l?, at-thc front end of the frame A, and within convenient reach of the foot of the driver on seat I. As the machincis drawn along, the grooves `d of the roller G receive the seed from the hopper and carry it over in the direction indicated by the arrow 1,

and discharge it upon the chute L, from which it fallsnin a scattered state Vupon the ground. '.lhe seed is harrowed in the ground by the teeth h, cach tooth being allowed `to rise and fall independently of the other, so that the teeth may conform to the inequalities of surface over which they may pass. The whole number of i teeth may be raised simultaneously a-t any time by actuating the lever P. Theroller G maybe thrown out of gear at any time hy raising the bar II, and thereby turning the pinion out of gearwith the'wheel E.

I-claim as new, and desire to secure by Letters `l."atcnt- 1. The roller G, provided with the grooves d and adjustable -bars e, in` combination with tho seedhopper Krand chute L, all arranged to operate substantially in the manner as and for the purpose set forth.

2. I also claim the harrow or covcringtocth h, attached to the bars M, which are fitted on tho rodN, in combination with vthe transverse bar N', arranged and connected to the lever l?, to .operate in the manner substantially as and for the purpose specified..

The above specification of my invention signed by me this fifteenth day of April, 1867.
